Nebulae

"Nebulae are the birthplace of stars. They are formed when very diffuse molecular clouds begin to collapse under their own gravity, often due to the influence of a nearby supernova explosion. The cloud collapses and fragments, sometimes forming hundreds of new stars. The newly-formed stars ionize the surrounding gas to produce an emission nebula. The nebula's gravity pulls the cloud inward and it starts to spin in the middle eventually gaining enough friction to be hot enough for nuclear fusion to occur. Other nebulae are formed by the death of stars; a star that undergoes the transition to a white dwarf blows off its outer layer to form a planetary nebula. Novae and supernovae can also create nebulae known as nova remnants and supernova remnants, respectively." (Wikipedia)

Outstanding gallery -- were scientists capable of seeing the gaseous columns before Hubble hit the skies 19 years ago? Lou
